The products is ad space, not the users
The product is the personal data Google packages up and sells to advertisers.
What shit, show me how I can buy some. Show me some that someone has bought.
If Google allowed it to actually be downloads, their competitors would be able to use it, so the processing is done within Google.
That doesn't make it any less of a product for advertisers.
Can you put just one link that show that Google sell data to advertisers?
